Example: Controlling Remaining Traffic
This example shows how to control remaining traffic from the remaining logical interfaces.
Requirements
Before you begin:
Review how to configure schedulers. See Example: Configuring Class-of-Service Schedulers on a Security Device.
Review how to configure and apply scheduler maps. See Example: Configuring and Applying Scheduler Maps.
Overview
To configure transmit rate guarantees for the remaining traffic,
you configure the output-traffic-control-profile-remaining statement specifying a guaranteed rate for the remaining traffic.
Without this statement, the remaining traffic gets a default, minimal
bandwidth. Similarly, you can specify the shaping-rate and delay-buffer-rate statements in the traffic control profile
referenced with the output-traffic-control-profile-remaining statement to shape and provide buffering for remaining traffic.
In the interface shown in Figure 1, customer VLANs 3 and 4 have no explicit traffic control profile. However, the service provider might want to establish a shaping and guaranteed transmit rate for aggregate traffic heading for those C-VLANs. The solution is to configure and apply a traffic control profile for all remaining traffic on the interface.
Example 1 considers the case where C-VLANs 3 and 4 have no explicit
traffic control profile, yet need to establish a shaping and guaranteed
transmit rate for traffic heading for those C-VLANs. The solution
is to add a traffic control profile to the svlan1 interface
set. This example builds on the example used in Example: Configuring a Four-Level Scheduler Hierarchy and does not repeat all configuration details, only those at the
S-VLAN level.
Next, consider Example 2 shown in Figure 2.
In Example 2, ge-1/0/0 has five logical interfaces
(C-VLAN 0, 1, 2, 3 and 4), and S-VLAN 0, which are covered by the
interface set:
Scheduling for the interface set
svlan0is specified by referencing anoutput-traffic-control-profilestatement, which specifies theguaranteed-rate,shaping-rate, anddelay-buffer-ratestatement values for the interface set. In this example, the output traffic control profile calledtcp-svlan0guarantees 100 Mbps and shapes the interface setsvlan0to 200 Mbps.Scheduling and queuing for remaining traffic of
svlan0is specified by referencing anoutput-traffic-control-profile-remainingstatement, which references ascheduler-mapstatement that establishes queues for the remaining traffic. The specified traffic control profile can also configure guaranteed, shaping, and delay-buffer rates for the remaining traffic. In Example 2,output-traffic-control-profile-remaining tcp-svlan0-remreferencesscheduler-map smap-svlan0-rem, which calls for a best-effort queue for remaining traffic (that is, traffic on unit 3 and unit 4, which is not classified by thesvlan0interface set). The example also specifies aguaranteed-rateof 200 Mbps and ashaping-rateof 300 Mbps for all remaining traffic.Scheduling and queuing for logical interface
ge-1/0/0 unit 1is configured “traditionally” and uses anoutput-traffic-control-profilespecified for that unit. In this example,output-traffic-control-profile tcp-ifl1specifies scheduling and queuing forge-1/0/0 unit 1.

CLI Quick Configuration
To quickly configure this section of the example,
copy the following commands, paste them into a text file, remove any
line breaks, change any details necessary to match your network configuration,
copy and paste the commands into the CLI at the [edit] hierarchy
level, and then enter commit from configuration mode.

Step-by-Step Procedure
To control remaining traffic with no explicit traffic control profile:
Set the logical interfaces for the S-VLANs.
[edit class-of-service interfaces] user@host# set interface-set svlan0 output-traffic-control-profile tcp-svlan0 user@host# set interface-set svlan1 output-traffic-control-profile tcp-svlan1 user@host# set interface-set svlan1 output-traffic-control-profile-remaining tcp-svlan1-remaining
Set the shaping and guaranteed transmit rates for traffic heading for those C-VLANs.
[edit class-of-service traffic-control-profiles] user@host# set tcp-svlan1 shaping-rate 400m guaranteed-rate 300m user@host# set tcp-svlan1-remaining shaping-rate 300m guaranteed-rate 200m scheduler-map smap-remainder
Results
From configuration mode, confirm your configuration
by entering the show class-of-service interfaces and show class-of-service traffic-control-profiles commands. If
the output does not display the intended configuration, repeat the
configuration instructions in this example to correct it.
[edit] user@host#show class-of-service interfacesinterface-set svlan0 { output-traffic-control-profile tcp-svlan0; } interface-set svlan1 { output-traffic-control-profile tcp-svlan1; output-traffic-control-profile-remaining tcp-svlan1-remaining; # For all remaining traffic } [edit] user@host#show class-of-service traffic-control-profilestcp-svlan1 { shaping-rate 400m; guaranteed-rate 300m; } tcp-svlan1-remaining { shaping-rate 300m; guaranteed-rate 200m; scheduler-map smap-remainder; # this smap is not shown in detail }
